Chemical Structure
Description
1,3-Cyclohexanedicarboxylic acid, 1-acetyl-4-oxo-, 1-ethyl ester (C12H16O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,3-Cyclohexanedicarboxylic acid, 1-acetyl-4-oxo-, 1-ethyl ester (CAS 2007916-26-7), molecular formula C12H16O6 and molecular weight 256.25 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
